put finger to keyboard and composed:

cannot get dun to work with aztech mdp3880-w(u) modem.

installed latest drivers, install went fine. "more info"
reported info from the modem.

When I try to dialout using dun i get : "error 633- modem is not
installed or configured for dialup, double click on the modems
icon in control panel"

When I do the above, it tries to reinstall the modem
drivers,even though they have already been installed.

Tried on of MS's solutions and rebuilt telephon.ini, still no
go. Also did their registry fix for telephon.ini

tried uninstalling and reinstalling drivers and modem still no
problem. Modem now assigned to com3 IRQ 10

in my Dell dimension bios, there is a section for all the irqs
where u set it to either available or reserved, but I was told
that this is only for non-plug and pray modems and I got a
message from windows saying this is plug and pray modem. IRQ is
currently marked available in bios.


Your modem uses a Rockwell/Conexant HCF (controllerless)
chipset. It's not a bad performer, at the very least it uses
much less CPU power than Conexant's softmodems (HSF).


tons of complaints about this modem on dell forum. Articles
detailing problems with it and it's drivers on the web (sorry 2AM
here not going to lookup the links). It is a win modem, not a real
modem. But this is besides the point really.


These are Conexant's generic drivers for HCF modems:
http://www.conexant.com/support/files/HCFp_Win9x.zip


Conexant says it is better to use mfg drivers and they cannot
guarantee their generic will work on various systems. I have two
driver packages of different release dates from dell at least one
of which supposedly came with the dell box. I also have a later
release for the same modem from a third party driver site. Looking
at the files they all look pretty similar-tried one from dell and
one from the third party, as I have already said-neither worked.
Or rather, I should say that win**** could not work with either.

This is the entry point for all other drivers:
http://www.conexant.com/support/md_d...ssistance.html

Your modem's properties, commands, and responses are located at
this registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\Class\Modem\
000n

I have exhaustively removed all references to this modem from the
registry after trying to remove the drivers from the
add/remove-now Win**** was not allowing me to remove the entry for
the enumerator package in add/remove. After getting rid of all the
reg entries that refered to both this specific modem and to the
driver files that were installed by it's driver packages, then add
remove no longer showed the entry. I also renamed all the driver
files in the windows/dir that were installed as a result of the
driver package installs. Rebooted and windows goes to: building
driver base, installing software for mdp modem, insert install
diskette-which i do not have-so maybe thepost saying that you
must have this to properly install the modem is true-then why does
dell give out a driver package for installing the modem at it's
site? Click cancel, but each time I reboot windows is asking again
for the install diskette for the modem. Windows also added two
registry keys for the modem after I had deleted them all that were
somewhat different from what was there before-one under
enum/root/unknown/0000 -unknown I guess because I cancelled the
driver install and control/asd/rob/root/modem/0000/mdp3880 pci
modem enumerator.

So the hardware is reporting it's presence to windows and windows
is modifying the registry even when I have cancelled the install
driver diskette process.

Maybe if I install the earlier versions of the drivers-the oldest
ones-it will work now, but not holding my breath. There was one
report from a fellow who said that windows complained that it
needed the older drivers, but I have not gotten any similar
errors.

One thing I did not report earlier is I was getting errors like
"failed to call enumproppages in modemui.dll" in safe mode. This
indicates from reading I have done that OS is not communicating
with registry for providing a user interface for setting modem
properties, which would explain the empty boxes next to com2 where
the modem name is supposed to be, even though the modem responded
normally to more info.



How does yours look?


That entry you mentioned was not there. There were a couple of
CSLID entries for a modem, but they appeared to be generic for any
modem and I left them alone.


If this key has a problem, then check the contents of the
modem's INF file. That's where the setup info comes from.


What should I look for there? Not really sure exactly how the inf
file interacts with the registry which interacts with allowing DUN
to create a dial out entry for the modem. And from the reading
I've done no one else has explained this on the net either.



Can you set up a comms session using HyperTerminal?


Did not try it. Infor from "more info" in my experience is the
same as what is shown for a normally working modem. It is just
that DUN cannot work with the modem. This could be a wrong driver,
but I am inclined to think at this point that there is some
special executable in the original modem install diskette that is
needed to install this piece of junk. But if that is true why does
dell offer the driver package. Maybe they expect all users to have
the original install diskettes or cd.


Here is a FAQ that may have useful info:
http://www.conexant.com/support/md_faqs.html


I've about had it and ready to buy another modem. Even for those
who had this modem running there were a multitude of complaints
about it=from slow speeds to disconnects to whatever and little or
no help from dell-that is why dell sells it's stuff so cheap-alot
of it is junk, imo. And posting at their forum site brought
nothing from their "tech support" people. Glad I only paid 15
bucks for this box instead of getting ripped off by Dell and then
STILL getting crappy support from them, as so many of the other
complainers on this modem have received.

IIRC, there is a special procedure to uninstall HCF/HSF drivers.

Here is an excerpt from the FAQ:

================================================== ===============
==== I would like information on drivers to install for both
modem enumerator and modem.

The installation instructions are packaged with the generic
drivers. Please refer to the readme.txt file for instructions on
how to remove and install the drivers.
================================================== ===============


Ok, I will check on that, thanks, but I think they are probably
referring to the method of removing old drivers from add/remove.

Here are two other sites that may be useful:

I thought aztec was out of business, all their other links are no
good.
